A 15Kg mass is accelerated from rest with a force of 100N. As it moves faster, friction and air resistance create an oppositely directed retarding force given by F_R = A + BV. where A = 25 N andB = 0.5 (N)/(m//s)At what velocity does the acceleration equal to one half of the initial acceleration ?

1.	A 15Kg mass is accelerated from rest with a force of 100N. As it moves faster, friction and air resistance create an oppositely directed retarding force given by F_R = A + BV. where A = 25 N andB = 0.5 (N)/(m//s)At what velocity does the acceleration equal to one half of the initial acceleration ?
